Weirdness happens when trying to access the Guidelines page from 2 different locations.
This video is about trying to access the page from https://discuss-space.wmflabs.org/c/events/l/map and then clicking on the Guidelines link in the banner - you just get the loading icon spinning forever.
This video is about trying to reach the page from the https://discuss-space.wmflabs.org/badges/16/read-guidelines badge page and then clicking on the Reading the community guidelines link - the result is just an empty page.
I have been able to replicate in my own Chrome semi-consistently. All the links point to https://discuss-space.wmflabs.org/guidelines from what I see. I can access Guidelines just fine from the main menu in https://discuss-space.wmflabs.org/ FWIW.
